If its length is 4x - 3 meters and its width is 2x + 6meters , what is the actual width of the rectangle?
1 answer:
Answer:
p
=
2
(
4
x
+
3
)
+

Explanation:
By definition the perimeter of an object is the length of all its sides.
Also by definition, for a rectangle the 2 sides of the width are equal and the 2 sides of the length are equal.
Therefore the equation for the perimeter of a rectangle can be written as:
p
=
2
⋅
l
+
2
⋅
w
where
p
is the perimeter,
l
is the length and
w
is the width.
Substituting what was given about the length and width gives the equation:
p
=
2
(
4
x
+
3
)
+
2
(
2
x
−
6
)
Simplifying this equation gives:
p
=
8
x
+

12
p
=
8
x
+

−

p
=

this one took me time lol
y = kx
6 = (k)(-7)
k = -6/7
y = -6/7 x
y = (-6/7)(4)
y = -24/7 = -3 3/7
Answer: y = -3 3/7
Hope this helps!
